Single Server multihomed Active directory wont route

[Guest]

I have a single server with two NICs
Net 1 Net 2
IP 192.168.1.1 192.168.2.1
MASK 255.255.255.0 255.255.255.0
GaTEWAY 192.168.1.254 ------

DSL on Net 1 192.168.1.254

Computer A on Net 1 can ping all except computer B
Computer B on Net 2 can ping 1.1 and 2.1 but cant get a response
from 1.254 which is the DSL router or Computer A

Seem routing is not working

DHCP has two zones Zone 1 assignes everything to 1.1
Zone 2 uses 2.1
I have tried every combination I can think of.
changing default gateways. Routing refuses to work. I even made the Registery change to enable IPForwarding. no joy

I read somewhere that Active directory can't use routing if the server is the root of the forest or is this balderdash???
I only have one server so is there a way?

tried adding a static route
route add 192.168.1.0 mask 255.255.255.0 192,168.2.1

Hi,

If I understand your network config it looks like:

ADSL --------------- Net1-------------------Server------------------Net2
192.168.1.254 192.168.1.1 192.168.2.1
255.255.255.0 255.255.255.0 255.255.255.0

If that is correct, then you should use gateway 192.168.1.254 on NET1 and
192.168.2.1 on NET2
Then you should use ICS or RAS on Server. Which means that you enable and
configure NAT on Server. Or just share 1.1 network to 2.1 network card.
This means that server will act like a router.
